Enhancing Surgical Performance: The Need for a Holistic View on Surgical Skills

Area of Science:

• Surgical Education
• Human Factors in Medicine
• Laparoscopic Surgery

Background:

• Surgeons utilize both technical skills (TS) and nontechnical skills (NTS) concurrently during operations.
• Existing research suggests potential interdependence between TS and NTS, but empirical correlation data is limited.
• Establishing a practical link between these skill sets is crucial for surgical training and performance evaluation.

Purpose of the Study:

• To investigate the relationship between technical and nontechnical skills in surgeons.
• To determine if this relationship exists overall and at the individual operating room (OR) team level.
• To assess the correlation between Objective Structured Assessment of Technical Skills (OSATS) and Nontechnical Skills for Surgeons (NOTSS) scores.

Main Methods:

• A cross-sectional, simulation-based study involving 3 surgical teams (2 surgeons, 2 OR nurses each).
• Laparoscopic interventions were video-recorded over 3 days in a simulated animal research setting.
• Pearson's correlation analyses were conducted on OSATS and NOTSS scores to evaluate skill associations.

Main Results:

• A weak positive overall correlation (r=0.336, p<0.05) was observed between OSATS and NOTSS scores.
• One team exhibited a moderate positive correlation (r=0.497, p<0.05).
• Correlations for the other two teams were non-significant (p=0.218) and nonlinear (p=0.872), respectively.

Conclusions:

• An overall relationship between technical and nontechnical skills in surgeons during simulated laparoscopic surgery was demonstrated.
• The inconsistent correlation at the team level highlights the significance of individual team dynamics.
• A holistic approach to surgical skills assessment is vital for optimizing surgeon potential in the OR.
